Jacob Frederick Brenckle
(14 November 1875– 26 June 1958)

NCU has cataloged about 25 fungi collected by Jacob Frederick Brenckle, who usually signed his collections as “J. F. Brenckle.”  Many specimens belong to “Fungi Dakotenses,” an exsiccate which contains about 675 specimens; it is unclear whether NCU owns a complete set.  A favorite collecting location of Dr. Brenckle’s was Kulm, North Dakota.

All NCU fungi, including those collected by J. F. Brenckle, can be found at mycoportal.org  .
As NCU continues to catalog our mycological collections using funds supplied by the National Science Foundation, it is likely that more specimens collected by Dr. Brenckle will be found.

“Upon completion of high school in Milwaukee [Wisconsin], Jacob Brenckle entered Milwaukee Medical College and later transferred to Northwestern Medical College where he was graduated in 1898.  In 1901 he married Amalie Boll [1875-1944] in Milwaukee.  They were the parents of three children, Arthur (at the time in Greeley, [Colorado], Dakotah (Mrs. Guy Le Fevre), and Mrs. Beatrice Davis [b. 1909], both from Northville [South Dakota]. 

Dr. Brenckle began his medical career in Webster, South Dakota, where he practiced one winter, then moved to Kulm, North Dakota.  During World War I, he enlisted in the Army, spending one year at Fort Douglas, Utah, and the remainder at Camp Pike, Arkansas, returning to Kulm after the war.  In 1923 he moved to Northville [South Dakota], where he stayed until the early 1930’s, then moved his practice to Mellette [South Dakota].

In botany Dr. Brenckle was recognized throughout the world as one of the leaders in that field, being credited with the discovery of two new flora species in South Dakota. 

As a widower he married a widow, Perle Jane (Elsom) Knickrehm [1893-1993], December 14, 1945, in Spink County [South Dakota]. 

A banquet was given in his honor and a medal presented to him by the South Dakota Medical Association in recognition of his 50 years in the profession…  Other interests and accomplishments of Dr. Brenckle over the years were:  building a home and office of stone in Kulm, North Dakota, developing a formula which he used to combat diphtheria, trapping and banding birds for the U.S. Biological Survey [sic; U.S. Geological Survey], and raising honey bees.  A box of comb honey which he entered in a national contest won first prize and was presented to the Coolidge’s while they were in the White House.” 1

Of the five taxa of Polygonum that Brenckle named (P. autumnale, P. interius, P. monteryense, P. oneillii, P. stevensii and P. utahense), only Polygonum utahense Brenckle & Cottam is still in use. 

Thus far I have found only one taxon of fungus that Jacob Brenckle named -- Hendersonia crataegi Brenckle (see Mycologia 10(4):  217.  1918.).

Many taxa were named in Jacob Brenckle’s honor, including the fungal genus Brencklea named by Austrian mycologist Dr. Franz Petrak (1886-1973).  Sadly, this genus has been subsumed into Scolecosporiella. 

Species (or varieties) named in Jacob F. Brenckle’s honor include:

Septoria astragali var. brencklei Sacc. (Pubished as ‘brinklei in Atti Memorie Accad. Patavina 33: 171. 1917.)  Some scientists currently recognize the variety; others do not and subsume it into the parent taxon. 

Bertiella brenckleana Rehm (Published in Annales Mycologici 9(4):  364.  1911.)  In 2016 recognized as Rosenscheldia brenckleana (Rehm) Theiss. & Syd.  (Published in Annales Mycologici 13(3-4):  649.  1915.)

Clypeoporthella brencklei Petr. (Published in Annales Mycologici 22(1/2):  149. 1924) In 1954 this was recognized as Diaporthopsis brencklei (Petr.) Arx & E. Mull.  (Published in Beitr. Kryptfl. Schweiz. 11(1):  372. 1954.)

Macrophoma brenckleana Sacc., Syd. & P. Syd. (Published in Annales Mycologici 11(3):  316. 1913) was revised to Discula brenckleana (Sacc., Syd. & P. Syd.) Petr. (Published in Annales Mycologici 22(1/2):  139. 1924.) Again revised to Chondroplea brenckleana (Sacc., Syd. & P. Syd.) Petr. (in 1956).  Currently it is recognized as Discula brenckleana (Sacc., Syd. & P. Syd.) Petr.

Diaporthe brenckleana Sacc. (Published in Mycologia 12(4):  202.  1920.)

Herpotrichia brenckleana Petr. (Published in Annales Mycologici 21(1/2):  16.  1923.)

Nectria brenckleana Petr. (Published in Annales Mycologici 23(1/2):  118. 1925.)

Patinella brenckleana Sacc. (Published in Mycologia 12(4):  203. 1920.) Currently recognized as Dermea brenckleana (Sacc.) Seaver (Published in Mycologia 25(2):  142. 1933.

Pezicula brenckleana Seaver (Published in North American Cup-fungi, (Inoperculates).  (New York) (3):  341.  1951)

Phaeotrype brencklei Sacc. (Published in Mycologia 12(4):  200. 1920.)

Solenia brenckleana Sacc. (Published in Riv. Accad. Di Padova 33:  163. 1917) was revised to Phaesolenia brenckleana (Sacc.) W. B. Cooke (Published in Beih. Sydowia 4:  122. 1961.)

Lophiostoma brenckleanum Sacc. (Published in Riv. Accad. di Padova 33: 166. 1917.)

Phomopsis brencklei Petr. (Published in Annales Mycologici 22(1/2):  151.  1924.)

Septoria brencklei Sacc. (Published in Annales Mycologici 11(6):  553.  1913.)

Sphaerophoma brencklei Petr. (Published in Annales Mycologici 22(1/2):  76.  1924.)

Trimmatostroma brencklei Sacc (Published in Annales Mycologici 12(2):  124.  1915.)

Jacob Brenckle’s daughter, Beatrice May (Brenckle) Davis (b. 1909) was a scientist in her own right, and wrote “A study of the microflora of Fargo Clay Soil,” to earn a Master of Science degree at North Dakota Agricultural College (now North Dakota State University) in 1932.
